Lieutenant Colonel General, in Serbo-Croat Генерал-Потпуковник or General-Potpukovnik (in Serbian literally "Sub-Colonel General"), is a rank in some armies, notably the Serbian Army and Air Force.
The rank of lieutenant colonel general represents a rationalisation of the situation in some armies of a lieutenant general outranking a major general, when a major outranks a lieutenant. In the Serbian Army, the rank of "sub-colonel" (Potpukovnik / Потпуковник ) is used rather than "lieutenant colonel" (Poručnikpukovnik / Поручникпуковникin).
In the Serbian Army and Air Force, it is the rank immediately below Colonel-General. The rank of lieutenant colonel general corresponds to command of a division.
In the Republic of Macedonia and Slovenia, a Lieutenant Colonel General (генерал потполковник and generalpodpolkovnik respectively) is the rank above Major General and below General, equivalent to a Lieutenant General.
